A Computer Marketed by Apple Inc. MAC which continually claims it just works must never use their own products or are referring to something else because MAC's OS are prone to crashes more than any other of its equivalent i.e. Windows XP, Vista, Linux. Mac also incredibly over prices their computers the MAC Book pro costs little under $3000, When the hardware that is included in that notebook is compared to that such as HP the Hardware is the same(if not online customizations can be made) and the price is only half as much. Anyone that says macs just works cause they are reliable are also in doubt. HP was named the most reliable computer of 2007. There is also no good games or software for macs seeing how they are one of the least used operating systems available. MAC's also constantly cheated their customers in the past making it so that if one wanted to use their OS they had to buy their computer which is why they overpriced such basic hardware, they also make their computers near impossible to upgrade unless you buy a MAC pro desktop which is extremely expensive as it is. I also find it funny how there $3000 computer comes with a 13' screen and any other Laptop comes with at least a 15' screen.I mean really they need to cheat you out of 2inches People need to open their eyes and understand expensive doesn't always mean best.

Mac: "Check out my new MAC book pro definitely the best thing to hit the computer user."
PC: "What are you stupid? you could have gotten the same hardware in any other PC for half the price... and if you really wanted could have bought OSX and it still would have been cheaper...Fucking retard"

Designed by Gordon B. Ingram, the MAC (Military Armament Corporation) series machine pistols were first designed in 1964. It is a simple machine pistol with few moving parts (making for easy maintenance) and a low cost of manufacture. The model 10 (AKA MAC-10) uses .45 ACP rounds, while the model 11A1 uses .380 ACP rounds and the model 11/9 is uses 9mm rounds. The MAC-11 series boasts a greater rate of fire due to the less powerful rounds, and can empty its impressive magazine in 1.57 seconds. It is essentially a spray and pray weapon on auto fire, since the rate of fire makes controlling the recoil (especially in the .45 cal series) extremely difficult. Its compact size, light weight, high caliber, large magazine, and blistering rate of fire make it an extremely lethal weapon with great stopping power in tight quarters
